JT/JT 420HDR 13/47 Chain Kit (OEM ratio) reinforced - standard steel sprocket

Designed for mopeds and small urban motorcycles, this JT DRIVE CHAIN kit maintains the original ratio of 13/47 for a straightforward and hassle-free replacement. The 420 pitch chain features a black/steel finish and incorporates XS-Ring seals, which minimize lubricant loss and provide better sealing of the links compared to a non-sealed chain.

• Type: JT HDR Chain, Racing quality
• Pitch: 420
• Seals: XS-Ring
• Sprocket: Standard steel
• Ratio: 13/47 (OEM)
• Color: Black/Steel

The reinforced kit is aimed at riders looking for a robust solution for urban use, both for restoration and for more intensive use. The standard steel sprocket provides wear resistance and ease of maintenance, while the HDR chain with XS-Ring seals contributes to smoother transmission and controlled wear if maintenance (lubrication and adjustment) is adhered to.
